Struct wasmer_engine_universal::UniversalArtifact

pub struct UniversalArtifact { /* fields omitted */ }

A compiled wasm module, ready to be instantiated.

Implementations

impl UniversalArtifact

pub fn is_deserializable(bytes: &[u8]) -> bool

Check if the provided bytes look like a serialized UniversalArtifact.

pub fn new(
    _engine: &UniversalEngine,
    _data: &[u8]
) -> Result<Self, CompileError>

Compile a data buffer into a UniversalArtifact, which may then be instantiated.

pub unsafe fn deserialize(
    universal: &UniversalEngine,
    bytes: &[u8]
) -> Result<Self, DeserializeError>

Deserialize a UniversalArtifact

Safety

This function is unsafe because rkyv reads directly without validating the data.

pub fn from_parts(
    inner_engine: &mut UniversalEngineInner,
    serializable: SerializableModule
) -> Result<Self, CompileError>

Construct a UniversalArtifact from component parts.

pub fn get_default_extension(_triple: &Triple) -> &'static str

Get the default extension when serializing this artifact
